<p class="MsoNormal"><strong>Summary:</strong> The Radon transform is used in generalizations of the original problem of recovering a function on the plane from its integrals over all lines in the plane. These transforms lead to many elegant mathematical problems, several of which are provided here (with separate solutions) for the avid problem-solver.</p></div></div></div>
